s anims.y (o1. astio-9133)"y Y This invention relates to Van improvedV form of mixing device of the same general nature as disclosed in my Patents 1,928,128 and.1,934,304, issued September 26, 19.33 and November 7, '1933, respectively. f Although the presentdevice is intendedespecially for the mixing of soap and water into suds for use in connection with the cleaning ofautomobiles, etc. yet it is to be understoodthat the invention as herein set forth comprehends any and all uses to which this Yform of structure may be put and is not limited to the mixing of soap and water, but may be employed in the mixing of other materials.

l One object of the present invention consists in devisingan improved form of means for spraying the-Water or other liquid upon theV soap or other material Within the container.

VAnother object consists in Aproviding, a means which is readily accessible from thev outside of the container Vso as to be capable of adjustment at any time for the purpose of varying theA pressureof the watery or other nuid as it is supplied to theYspraying-means located Within the.I container and for the purpose also of thereby vary-A ing the speed of movement of the-spray device which is rotated by the force ofthe uid.

Another object consists in devising an improved form of discharge means extending from, the lower end of the container to the outlet thereof.

Ariurther object consists in devisingan irnproved structure and arrangement of perforated tubular member through which the solutionof soap and water or other materials passes and which may be located upon theonev side of .the container with direct discharge connection to the outlet at the bottom of the container. Y g Y Other objects will appear from the following description and claims when considered rtogether with the accompanying drawings. I It is to be understood that the present disclosure is merely for purposes of illustration and that other modifications and variations may be made Without departing from the spirit of the inven tion as herein set forth and claimedf Y i "Fig, 1 is a vertical sectional view taken on line I-I of Fig. 2; Fig. 2 is a top plan view according tol line 2-2 vof Fig. 1 Fig. 3 is taken on line 3-'-3 of Fig. 1; Fig. 4 is avertical sectionalview of a modication taken on line 4-4 of Fig. 5; and Fig.v5 is a top plan View according to line 5-5ofFig4. a I, Inthe'form of device illustratedin Fig.` 1 of thedrawings, the main body of thezcontainer Iy has araised bottom 2 which supports thecen-V trallyn disposed perforated Vtubular member. 3 which is supported by the bottom 2 and which registers with avcentrally disposed opening in the bottom 2. The soap or 'other material is adapted to be placed within the container and to surround `5 the tubular member 3; Y if; Upon thev closure 4 of the container, there is mounted the nozzle 5 through which extends-a passage-for supplying water or other liquid to the inside of the container., Swivelly mounted upon the inner Iianged end of the nozzle 5, which extends throughthe cover 4, isa spraying device B which comprises a hollow arm extending diametricallyiofjthe container and which is provided atitsftwoopposite ends with thespray attach- 15i ments `'I ,extending in opposite directions V:at ,a' slightyangle and transversely to the member `6.

. Thispdevice is'so KVconstructed and arranged that the forceof the wateror other liquid as it enters through thenozzle 5 and into the two radially dis,- posedarms of the member 6, will thereby auto'.4 matically cause rotation thereof about 'its `swivel connection.; Also, the water or other liquid will at thevvsame stime be'sprayed from the attach@ ments 'l onto the top ofthe soap or other material which iscontained within the container I.4 y ,I 'I'hevalvey connection 8 of any suitablestandf ard; form may be attached to the nozzleY 5,'and asuitable form of vhose or tube connection may beattached tothe outer endof the valve'connection 8,.; valvemay be opened'andrclosedby means of-thehandle 9 and it is to be understood thatuthe present invention is not limited to the particular typev of valve herein illustrated but `any otherk form of suitable valvemay be employed vat this point, asv for instance, that disclosed inmy co-pendingappli ation, Serial No. 507313 above referred t0. ASk a meansoi varying the pressure ofthe water vorcther iiuid aspit is supplied to the rotatable 40. arm 6, IY have provided the screw-threaded plug form of valve l0 which may be set at any time so as yto ,obtainV the pressure desired through the noz# zle 5,; In thisway, there may be obtained not only y the proper degree of pressure for properlyrdis- 45 solving the soap or other material withinthe container but also the speed of rotation of the spray device (if may be varied by regulation of the screw plug Il). 'A j Attached to theunder side of the raised bottom l2 and extending. radially thereof is the tubular vformed ldrain member l I which extends from@ point beyond the lower end of the tubular mem-` ber3. to the opposite side of the Wall of the containerbelowthe bottom 2 Aso as to communicate 55'v with the goose-neck form of outlet I2. This drain member I I may be pressed out of sheet metal and attached to the bottom 2 in any suitable manner, as for instance, by welding. The bottom 2 is raised to a suliicient degree to aiord suitable housing for the drain member I I.

The plug I3 closes an opening through the wall of the container I near the bottom of the main portion ofthe container wall I through which access may be had at any time for ascertaining when the supply of material within thecontainer needs to be replenished.

With the form of device as above described, the force of the water as it enters through the open valve 8 and past the adjustable plug I0 will cause the spray member 6 to rotate about the vertical axis of the container and the water will be sprayed out through the attachments 1. The water as it is thus sprayed upon the top of the soap or other material within the container will be dissolved thereby and the mixture of soap and water will find its way through the apertures in the member 3 through which it will pass by gravity down through the bottom central opening and along the inclined bottom I I for discharge through the goose-neck I2. When the valve 8 has been fully opened, the force of the flow of water can be varied by adjustment of the plug ID during operation of the device. In this way,the quantity of water thus delivered to -the container can be varied so as to obtain the proper consistency of water and soap solution and at the same time, the speed of rotation of the swivelled spray member 6 can be regulated. When it is desired to discontinue use of the present-device, the valve 8 will be closed and practically immediately the tube 3 and the bottom discharge member II will be emptied of the soap and water solution and the device will remain in such condition until the next operation. As a result, soap and water solution will not stand in the bottom of the device durlng periods of idleness.

In the modified form of device illustrated in Figs. 4 and 5, the false bottom of the container I is omitted and there is provided a substantially half tubular member'3a upon the one side of the upright wall of the container. That is, the -mernber 3 is of substantially semi-circular cross section. This tubular member extends throughout the full height of the container, that is, from the bottom I4 to the top I5 and the goose-neck IG is provided in the wall of the container at a point adjacent to the lower end of the tubular member. In this form of device, the plug I1 which closes the opening near the bottom of the container for ascertaining the quantity of its contents, is located upon the opposite side ofthe container, as clearly indicated in the drawings. l

In all other respects, the construction Yillustrated in Figs. 4 and 5 is the same as in the first form of device illustrated in Figs. 1, 2, and 3; that is, the spray device is of the same form except that it is of shorter length because the perforated tubular member in this modified form of device is located to one side of the spray device 6. v

When using the modied form of device illustrated in Figs. 4 and 5, the valve 8 will be opened so as to permit the water or other fluid to be sprayed by the attachments 1 upon thesoap or other material within the container I. As in the other form of device, the screw plug I0 may be adjusted so as to regulate the force of ilow as well as the speed of rotation of the swivelled spray device 6. The soap andwater solution thus formed will find its way through the apertures in the upright tubular member whence it will flow out through the goose-neck I6.

With the particular combination of spray device including the swivelled spray member, there is realized the full beneiit of the spraying of the water upon the body of soap without, however, requiring the provision of a circular spraying pipe or other such spray device which requires a more extensive construction than that herein disclosed. In other words, the automatically rotatable spray device which consists merely of a single form of diametrically disposed arm, constitutes a decided simplification of other spray devices which have been heretofore employed. At the same time, there is obtained uniform spraying of the water over the entire top surface of the soap.

Another advantage consists in the possibility of varying the degree of flow of the water at any time during operation of the device. Also, this means for regulating the pressure of flow may be employed without involving any modification in the other valve structure 8 which may be of standard form and hence requiring no special design of valve for the purpose of the present device.

The particular construction of means for draining the soap and water solution from the container affords the further advantage of avoiding accumulation and standing of soap and water solution in the container when not in use.

It is to be understood that the several features hereinbefore referred to or modincations thereof, may be employed together as parts of the same unitary combination or they each may be employed in other combinations with other corresponding elements of modified or different construction. Therefore, the following claims are to be understood as covering the several features of invention herein set forth, either in their specific construction and combinations as herein disclosed or in modified forms, and as parts of other combinations without being limited to their association with the specic detailed construction of the other features of invention also disclosed in the present application. y
